Default Boost controller questions?

I bought a turbo kit used off a fellow memeber on these boards. The kit is a ludespeed stage 2 kit. With the kit is a deltagate wastegate. My question is can i run a boost controller, say electronic along side with the wastegate and have the wastegate set at the highest boost i want it to go if the boost controller fails? If so how do i do this and install it to work with one another? Thanks

It is generally not recommended to use a EBC or MBC on a low boost application as it is a recipe for disaster.

Use the wastegate spring you have or upgrade it, but playing with fire usually gets you burnt... do some reading in here, plenty of blown engines..

what about in a higher boost situation, say 12-20psi?

Let's make some assumptions before I answer that...

1. The engine has been built (low compression pistons and upgraded rods)
2. Proper fuel system (rails, injectors, pump)
3. Engine management (Link or TEC-x)
4. Tranny (clutch and flywheel too) that could handle the power.


Yes, a EBC would be perfect. I used a HKS EVC V for about 7 months before I switched over to a Blitz unit. No reason other then better matching color on the Blitz. No spikes on either. Multiple settings on either. Work like a charm.

I used a TXS dual stage MBC for a while and didn't like trying to tune the car boost wise by pulling over, popping the hood and dealing with the heat... which is how I ended up with the HKS...

In my case, i have the ej22t, so the higher boost shouldn't pose a problem. I'm thinking about Profec-e01 and emanage. Need to do parallel rail mod and bigger injectors first though.

(I have Eric's old car)

oh, and also, why is it a bad idea to use EBC in low-boost application?

The potential for damage is higher with a MBC then a EBC, but you do have to set it up, now don't you? What if you have a hose or switch set incorrectly? I know, 25psi instantly with a Greddy Profec B. 18psi with the HKS unit when installing it for the first time...

It comes down to this... The wastegate spring prevents you from blowing up. Great for low boost. MBC / EBC means you have to setup the boost level, which introduces a new layer of variables to your setup. Thus increasing the chances of *BLAMO* time..

The MBC is worse then the EBC, since they are very touchy. Aaronb and I were using one on his low boost setup, and turned the dial on it about 1/50 of a full turn. That went from 7psi to 15psi. Result? 8 months of downtime and a engine rebuild(pistons & rods).

While everyone claims that MBC is bad the right MBC can do the job nicely. I am using the Hallman Pro RX. It uses a ceramic ball and a super soft spring the most it can raise the boost above wastegate is 4-5psi. It is purposely built for low boost kits. It takes me about 2- 360 full rotations of the knob to get 1psi. Check this website Bootcontrollers.com This is where I got mine.

Now, with this turbo kit (ludespeed stage 2) there's nothing for a boost controller to control is there? What i mean is there's nothing to attach the solenoid to (not that i've seen anyway) so that it can cut boost. What else would we need to buy to get an EBC or MBC working?

thanks.

I've learned a lot in the last month, but i've still got a long way to go

throw the solenoid in-line anywhere onto the wastegate vaccum line.

I am getting the SBC-Id, it is in the mail now, i'll post a detailed install afterwards.

Sorry, I didn't mean to incinuate (sp) that MBC's were bad in rerads to them not working or anything like that. I think MBC's are great, for higher boost applications (<7psi). I think EBC's are great for the same reason.

Personally, the perpensity for destructive events is too high when using a BC on a low boost application. I've seen it happen too many times.

So someone running say 17.5+ PSI would probably be better served with an MBC/EBC than trying to wrestle with the stock boost controller?

You didn't just bump an almost 3 year old thread, while posting in the wrong forum did you?

That would be correct.
